These are some images for Clarkson University junior lab, project 1 from spring 2005.
For this lab we had to design and build a traffic light controller using only discrete digital chips.
The traffic light scenario is an intersection between a heavily traveled highway and a country road with pedestrian crossways. The highway has a higher priority over the country road, and a pedestrian has the highest priority.
The design used a state machine to determine which road was allowed to go based on the inputs to the system from buttons representing cars on the country road and a pedestrian waiting to cross.
I enjoyed this lab; it's really crazy to see the aftermath of three breadboards and two weeks of work.

First semester senior year for computer engineers at Clarkson University is EE416, affectionately named "Senior Design Lab", nicknamed by the students "Damn that was fun, but I don't know if I would do it again". The focus of the lab is to do a semester long design project incorporating almost all aspects of computer engineering.
The 2005 senior lab project was to design a "robotic retriever" robot to semi-autonomously navigate an unknown course, controlled by a base station using a bluetooth link. The major aspects of the project included developing a GUI program to control the robot and writing embedded C code for the FreeScale HCS12 microcontroller mounted on the robot.
The course also required five major milestone reports periodically along the design at key points.
I found these pictures while clearing off my phone and thought it apt to post on here. I am going to contact the people in my group and see if I can get some better pictures of the bot, and maybe some video too!

This is a cheap 2x16 character parallel LCD that I ordered last year. Over the summer I hooked it up to the parallel port of a laptop as a display for playing MP3s. This year in school I built another version of the connection so that the LCD can be mounted in the bay of a computer.

As some might have seen, the other day I posted the video for the disco bar found on hackaday.com. This video is cool, and shows what can be done with free time and RGB LEDs.
While I was watching the video I thought of some posible extensions for the bar. If one were to use a piezoelectric sensor to indicate pressure you could make the bar change colors when people pressed on it or as drinks moved.
Now THAT would be cool, a fully intractive bar! Also could tie this in with the Bar Monkey ( http://www.barmonkey.net/ ) and REALLY have a kickin party!

I was crawling the net the other day and found this Windows Vista commercial. One site said this is the commercial to 'Officially announce' the name of the next version of Windows to the masses. It is uploaded in the coolstuff section. I don't know, to me it seems kinda weird to make a commercial for Windows Vista stressing clarity when the entire commercial is hazed with light and excessive lens flares, lol.

Steve Wozniak is viewed by many computer engineers as an idol. The co-founder of Apple computers with Steve Jobs and the main creator of the first Apple PC, Woz as he is called, was a computer genius of his day. I know I respect the innovation the man provided to the fledgling personal computer industry back in the early 80s. Slashdot.org yesterday posted a link to an interview with the rather media shy Woz. It's an interesting read about the current state of Apple computers and Micro$oft. Check it out!

Apple and Woz’s story is also retold in the movie Pirates of Silicon Valley
